The CX20865 far-field voice input processor SoC
is designed for voice interactive applications including smart TVs.
The device includes 24-bit A/D converters, quad microphone input
paths, automatic speech recognition engine, powerful dual-core
32-bit DSP, and power management functions.
The 9 x 9 mm BGA packaged chip uses proprietary
far-field voice pre-processing algorithms and supports stand-alone
wake-on-voice functionality. It has Selective Source Pickup
technology that maintains speech recognition in the presence of
random ambient interference. The device has full-speed USB and I2S
I/Os for voice data, and I2C and UART interface for control. (From
